[Bug 2069821] [NEW] [VROC] [Ub 24.04] mdadm: buffer overflow detected

[Kinga Tanska]

Public bug reported:

Mdadm throws buffer-overflow sometimes, it depends on the building environment.
It happens mdadm is built with FORFTIFY_SOURCE=3 (as it is done in Ubuntu 24.04).

Buffer-overflow is detected for many commands in this case:
- mdadm --detail-pl
- mdadm -CR /dev/md0 -l1 -n2 /dev/nvme0n1 /dev/nvme1n1
*** buffer overflow detected ***: terminated
Aborted (core dumped)


It is fixed in mdadm upstream - please apply this patch to mdadm package and rebuilt it.
